Aaron Hernandez spent a weekend with friends in Newport, R.I., renting jet-skis and scooters, just four days after allegedly murdering two people in the South End of Boston, according to a beach rental shop owner who spoke with NewsCenter 5.

"I had his picture up in my shop. Everybody was like, 'Oh, that's cool,'" Thomas Welby told NewsCenter 5's Liam Martin on Saturday night. Welby owns Scooter World in the Rhode Island vacation town. "And then the next year I took it down, because it's not good for business."

Welby said Hernandez, then a Patriots star tight end who had just signed a multi-year, $40 million contract, walked into the shop July 21, 2012.

"He took pictures with us. He was cool," Welby recounted.

He said Hernandez and three friends rented four scooters and four jet-skis, and didn't seem to have a care in the world.

Hernandez, according to Welby, came back to the shop when he lost one of the keys.

"And he was really apologetic about it: 'Sorry, sorry,' you know," Welby said.

"It was kind of crazy to me that he would care about a little scooter key after what he had just [allegedly] done."

The visit came less than a week after the July 16 double-murder outside of the Cure Lounge in Boston. Hernandez was indicted Thursday by a grand jury as the gunman in that case, accused of killing Safiro Furtado and Daniel de Abreu after an altercation in the club.
